摘要	Hizikia fusiformis is one of the important commercially cultivated seaweeds in China. Inter-simple sequence repeats (ISSR) and sequence-related amplified polymorphism (SRAP) markers were used to assess genetic structure of nine wild H. fusiformis populations collected along the coast of China. Of the 255 bands generated by 21 ISSR primers, 99.61% were polymorphic and 99.71% of 344 bands amplified by 30 SRAP primers were polymorphic. The tested high genetic diversities show that the average Nei's genetic diversity (H) were 0.1519 and 0.1624, and average Shannon's information index (I) were 0.2248 and 0.2400 in ISSR and SRAP analyses, respectively. Unweighted pair group method with arithmetic mean (UPGMA) dendrograms of the nine populations were divided into two main groups. The ISSR and SRAP analyses values of gene differentiation (G (ST), 0.5955, 0.5486, respectively) indicate that high variation exists among the nine populations, likely due to external interferences and limitation of gene flow (N (m) = 0.3397, 0.4114). Our study indicated that human activities and herbivore overgrazing had influenced the natural Hizikia populations and that the understanding of population genetics would be helpful in sustainable utilization and biomass conservation of Sargassaceae resources.
